Claims.

This invention relates to certain new and useful improvements in a combined jack and bumper for automobiles, this application being a furthering of the subject matter presented ,5 ilnzmy Patent No. 1,737,720 granted December 3,

The primary object of the invention is to simplify the invention disclosed in myv prior Patent No. 1,737,720.

Another object of the invention is to provide the jack with an ornamental wrench or head.

Anotherz object of the invention is in providing a combined jack and bumper with an improved impact member.

E5 Another object of the invention is to provide the vehicle with an improved bumper supporting arm.

Other and further objects will appear in the specification and be specifically pointed out'in the appended claims; reference being had to the accompanying drawings, exemplifying the in- Ventiomand in which:

Fig. 1 is a fragmentary plan view of the rear portion of an automobile showing the combined jack and bumper attached thereto.

Fig. 2 is a front view of Fig. 1 showing the jacks in a running position. 4

Fig. 3 is a view of one of the jacks in a lifting position, and one of the hearings in section showing the bumper locked by the spring plunger.

Fig. 4 is a side elevation of Figs. 1 and 2.

Fig. 5 is an'enlarged vertical section of the bumper jack. 7

Fig. 6 is an enlarged view of a gear box and gears for operating the jack.

Figs. 7 and 8 are modifications of the different ways of mounting the jacks on a vehicle.

Referring by numerals to the accompanying drawings, I designates the side frames of the vehicle chassis and secured to the rear end of each frame by a bolt 2 is a rear spring 3, said springs being mounted on the rear axle housing i.

The disclosure of this improved combined jack and bumper is shown as applied to the rear end of the vehicle or automobile, although the ap plication thereof can be to the front of the vehicle as well.

The wheels 5 of the vehicle are supported from the axle 4 in the usual manner and extending forwardly from each frame I and secured thereto by bolts or rivets 6 is a bumper supporting arm 1. The forwardly extending end of each arm I is formed into a bearing 8, said bear- 'ings being slotted and having ears 9 formed thereon, extending through said ears are bolts l0. Extending approximately half way around the inner circumference of said bearings are grooves I l and in one of said bearings isa spring 5 plunger l2, and mounted in said bearings is a bumper l3.

The bumper I3 is of tubular construction and isprovided with a pair of stop pins M, said pins are adapted to turn withthe bumper l3 in the grooves H of thebearings 8 tori-stopping said bumper in different positions. The bumper is further provided with openings M for the reception of jacks l5. The lifting jacks comprise tubular lengths Hithreaded at one end, and mounted over said lengths are tapered jaw sleeves H. The tubular lengths I6 extend through the openings l4", tapered jaw sleeves [8 are loosely fitted over the lower part of each of said tubular lengths 56, a washer I9 is placed over the ends of the tubular lengths IS, a cap is mounted over the washer I9 and screwed to the tubular length i6 locking said tubular length I6 and washer it in position. The cap 20 is provided with an opening 2| which is larger than the opening in the washer Hi, this opening 2| is for the reception of a knob 22, mounted in the opening of the washer l9 and cap 20 is an extending end of a telescopic screw 23", the extending end of said screw being secured to 'the knob 22 by a pin 2d, said knob engaging one side of the washer l9 whereas a collar 22" on the screw 23" engages the opposite side of said washer. Mounted within the tubular length I6 is a tubular leg 25, one end of said leg having a threaded opening 26 for the reception of the telescopic screw part 23, the other end of the leg is provided with an ornamental head 21 screwed or otherwise secured thereto, mounted over the tubular leg 25 is a loosely fitted slidable sleeve 28. For preventing the tubular leg 25 and the slidable sleeve 28 from turning with the telescopic screw 23", said leg and sleeve are provided with flat sides 29 extending up to approximately one inch from the ends thereof, the 5 round ends limiting the travel of said sleeve and leg. The tubular length l6 also has a flattened portion 30 for preventing said sleeve and leg from turning and from being forced out of the tubular length l6 when the tubular leg 25 reaches its lowest point of travel. The knob 22 is provided with an opening 22 for the reception of an operating wrench 3!. I do not want to be limited to this particular structure however, as a gear may be mounted on the end of the screw 23" and in the cap 2|!" as shown in Fig. 6. The bumper I3 is provided with a pair of openings 32 for the reception of the spring locking plunger H. The bumper l3 is further provided with an impact member 33 which is bolted to the bumper|3 by bolts 34.

When the vehicle equipped with .this improved combined jack and bumper is traveling, the tubular lengths I6 are in a vertical position as shown in Figs. 1 and 2. When the jacks l5 are held in a vertical position during the travel of the vehicle the stop pins l4 engage the upper ends of the grooves II and the plunger |2 is in one of the openings 32, looking the jack in a vertical position.

To operate the jacks l5 for changing tires or making other repairs, the knob l2" on the plunger I2 is pulled outwardly by the operator until the plunger |2 disengages the opening 32 in the bumper bar l3. The operator holds the plunger |2 out of the opening 32 with one hand and grasps one of the Jacks IS with the other hand thereby pulling the jack forwardly, thus turning the bumper l3; as soon as the opening in the bumper |3 passes the plunger |2 the operator releases the knob |2 on the plunger |2 allowing the plunger to ride on the outer periphery of the bumper l3 at the same time the operator continues to pull the jack forwardly and downwardly until the jacks |5 again assume a vertical position. When the bumper I3 is in this position, the stop pin M which is clearly shown, in Fig. 7 engages the other end of the groove H and the spring plunger l2 drops in the other opening 32 thus locking the bumper in operative position for raising the vehicle as shown in Figs. 3 and 7.

In this position the knob 22 will be uppermost and the polygonal end 3|" of the wrench 3| can be engaged in the opening 22' in the knob 22 as shown in Figs. 3 and 5. When the jacks l5 are in the position shown in Fig. 3, the jacks are ready to be operated downwardly and by reason of the screw 23". having a left hand thread, the wrench 3| when turned in a right hand direction will cause the telescopic screw 23" to force the tubular leg 25 and the slidable sleeve 28 downwardly, forcing the ornamental head 21 against the roadway thus raising the vehicle sothat repairs to tires or other parts can be made.

After repairinga tire or other parts of the vehicle, the wrench 3| is manipulated so as to draw the tubular leg 25 and slidable sleeve 28 into the tubular length Hi. The spring plunger I2 is then withdrawn from the opening 32 by the operator and the bumper I3 is then turned until the tubular lengths I6 again assume a vertical position as shown in Fig. 2. The parts for looking the bumper l3 in the different positions are clearly shown in Fig. 7.

Figs. 7 and 8 are modifications of the different ways of attaching the jack to the bumper parts. One of these jacks shows a single lifting screw in place of the telescoping screw shown in Fig. 5. However, telescopic screws may be used in either jack.

Fig. 'l is an enlarged vertical section of one of the jacks mounted in one of the bumper arms I, taken on line of Fig. 2, but showing the modified 'jack in lifting position and the bumper jack locked in difierent positions.

The modified jack l5" shown in Fig. 7 comprises a tubular length l6", one end of the tubular length I6" is turned down so as to form a shoulder 8" and on said turned down portion is a screw thread.

) The tubular length. I6" is mounted in the cy-' lindrical opening I which is formed in the bumper arm 1 so that the shoulder 8" on the tubular length engages one end of the cylindrical member 1" whereas a screw threaded sleeve I8" is 42 whereas a collar 4lon the screw 44 engages the other side of said shoulder. Mounted within the tubular length I6 is a tubular leg 25". The tubular leg 25" is the same as the one shown in the enlarged section Fig. 5 with the exception that the screw opening is for a single screw in place of the telescopic screw 23" and the leg 25" is provided with a longitudinal slot 48 in place of the flat side 29. The tubular length I6" is provided with a pin 49 which prevents the tubular leg 25" from turning when the tubular leg 25" is moved longitudinally in the tubular length I6". The jack I5" is further provided with a third tubular leg 50, said leg is provided With a longitudinal slot 5| and a series of circumferential slots 52. The leg 50 is further fitted with a base 53, the tubular leg 25" is provided with a pin 54, the tubular leg 50 slides longitudinally and circumferentially on the pin 54. The tubular leg '50 is adapted for quickly adjusting the jack to a lifting position. To operate the lifting jack, the leg 50 is turned until the pin 54 is in the longitudinal slot 5|, the tubular leg 50 is then lowered until the base 53 of said leg engages the roadway, the leg 50 is then turned circumferentially until the pin 54 engages the closed end of one of the circumferential slots, the jack is then ready for lifting the vehicle. An ornamental Indian head wrench 55 having a socket 56 formed therein is mounted over the hexagon nut 45. After the tubular leg 50 is adjusted, the Indian head is spun around turning the screw and causing the tubular leg 50 to force the base 53 against the roadway, thus raising the vehicle. To return the jack to anormal position the Indian head or wrench is spun in a reverse direction until the base 53 disengages the roadway, the leg 50 is then turned until the pin 54 engages the longitudinal slot 5|, the leg 50 is then forced up until the pin 54 is in alignment with the lowest circumferential slot, the leg 50 is then turned back until the pin again engages the end of the circumferential slot, the Indian head is then again turned until the base 53 engages the end of the tubular length l6", thus locking the jack in normal or running position as shown in Fig. 4.

Fig. 8 shows a tubular bumper of the 'same construction shown in Figs. 1, 2 and 3 and operates in the bumper arm bearings 8 the same as the bumper l3, however the bumper shown in Fig. 8, is a straight bumper and does not have the rounded or curved ends shown in Figs. 1, 2 and 3 and the ends of the bumper are open for the reception of the shank 58 of the tubular T 51. One branch of he T 51 is curved so as to form the rounded en of a bumper, and the T is secured to the endiof the bumper l3 by means of the shank 58 which is a part of the T 51. A pin 59 extends through the bumper and shank so as to prevent the shank from turning in the bumper. It is to be understood that the section shown in Fig. 8 is but one end of the bumper and that I with a T 51. Obviously if a jack is mounted in each end of the bumper, the intermediate jacks shown in Figs. 1, 2 and 3 are to be ehminated. One end of the vertical branch 01." the T I! is provided with a washer or shoulder l9" and surrounding said shoulder is a rounded cup shaped member 58" having an opening 80. The other end of the T I! is open for the reception of the telescopic screw 23", tubular leg 25 slidable sleeve 28 and ornamental head 21. The cup-shaped member 58" is for the reception of the knob 22. The telescopic screw 23 tubular. leg 25 slidable sleeve 28 ornamental head 21 and knob 22 are the same type parts shown in Fig. 5 and are inserted in the T 51 the same as shown in Fig. 5. The extending end of the telescopic screw 23 is inserted through the opening in the shoulder l9, the knob 22 is mounted over the end 01' the screw 23", and secured thereto by a pin 24 or by any other suitablemeans. In other words with the exception of the rounded cup shaped end 58" and the means of attaching the jack to the ends of the bumper the jack is almost identical to the jack shown in Fig. 5.

Various modifications may be made in this invention without departing from the spirit thereof, and therefore the exact forms shown are to be taken as illustrative only, and not in a limiting sense and it is desired that only such limitations shall be placed thereon as disclosed in the prior art. I
